先, 针对单个智能体系统设计未知输入观测器以消除干扰项对状态估计的影响. 参考Kalman滤波器算法来求解状
态反馈矩阵, 使得输出残差信号的协方差最小, 从而增强系统对随机噪声的鲁棒性. 然后, 基于观测器的状态估计
信息, 设计了鲁棒一致性控制协议, 并将其转化为线性矩阵不等式求解问题. 最后, 通过一个数值仿真证明了所提方
法的正确性和有效性. |
| 英文摘要 |
| Most of the existing research results only consider the single existence of random noise or unknown input
interference. In actual engineering, both often exist at the same time. In the context, This paper proposes a consensus
control protocol method for a class of nonlinear multi-agent systems with unknown input interference and random noise.
First, an unknown input observer is designed for a single agent system to eliminate the influence of interference items on
state estimation. Refer to the Kalman filter algorithm to solve the state feedback matrix to minimize the covariance of the
output residual signal, thereby enhancing the system’s robustness to random noise. Then, based on the state estimation
information of the observer, a robust consensus control protocol is designed and convert the problem into a linear matrix
inequality problem to solve it. Finally, a numerical simulation proves the correctness and effectiveness of the proposed
method. |
